“The riddle does not exist. If a question can be put at all, then it can also be answered.”

“We feel that even if all possible scientific questions be answered, the problems of life have still not been touched at all.”

“What can be shown, cannot be said.”

“[Philosophy] must set limits to what can be thought; and, in doing so, to what cannot be thought. It must set limits to what cannot be thought by working outwards through what can be thought.”

“The real question of life after death isn't whether or not it exists, but even if it does what problem this really solves.”
